Cisco NCS 4201 and Cisco NCS 4202 OverviewThe Cisco NCS 4201 and NCS 4202 Network Convergence Systems are full-featured, compact one-RU highconverged access platforms designed for the cost-effective delivery of TDM to IP orMPLSmigration services.These temperature-hardened, high-throughput, small-form-factor, low-power-consumption systems areoptimized for circuit emulation (CEM) and business applications. NCS 4201 and NCS 4202 chassis allowservice providers to deliver dense scale in a compact form factor and unmatched CEM and Carrier Ethernet(CE) capabilities. They also provide a comprehensive and scalable feature set, supporting both Layer 2 VPN(L2VPN) and Layer 3 VPN (L3VPN) services in a compact package .

For more information on the Cisco NCS 4201 Chassis, see the Cisco NCS 4201 Hardware Installation Guide.

For more information on the Cisco NCS 4202 Chassis, see the Cisco NCS 4202 Hardware Installation Guide.

C H A P T E R 2New Features in Cisco IOS XE Everest 16.5.1

This chapter describes the new features supported on the Cisco NCS 4200 Series with Cisco IOS XE Everest16.5.1.

• New Software Features for NCS 4201 and NCS 4202 in Cisco IOS XE Everest 16.5.1, page 5

• New Hardware Features for NCS 4201 and NCS 4202 in Cisco IOS XE Everest 16.5.1, page 6

New Software Features for NCS 4201 and NCS 4202 in CiscoIOS XE Everest 16.5.1

• BFD on IP Unnumbered Interfaces

• The Cisco NCS 4200 Series now support BFD to run on IP unnumbered interfaces, which take the IPaddress from the loopback address. You can use the same loopback address on multiple interfaces. Formore information, see IP Routing: BFD Configuration Guide, Cisco IOS XE Everest 16.5.1 (NCS 4200Series).

• Support for Optic ONS-SI-2G-S1The ONS-SI-2G-S1 is supported on the 1-Port OC-192 or 8-Port Low Rate CEM IM.

• Support of Adaptive Clock Recovery (ACR) on 8-port T1/E1 Interface Module

Adaptive Clock Recovery (ACR) is most commonly used for Circuit Emulation (CEM). ACR is anaveraging process that negates the effect of random packet delay variation and captures the average rateof transmission of the original bit stream. ACR recovers the original clock for a synchronous data streamfrom the actual payload of the data stream. In other words, a synchronous clock is derived from anasynchronous packet stream. ACR is a technique where the clock from the TDM domain is mappedthrough the packet domain. Effective Cisco IOS XE Everest 16.5.1, ACR is supported on 8-port T1/E1interface module.

For more information, see 1-Port OC-192 or 8-Port Low Rate CEM Interface Module ConfigurationGuide, Cisco IOS XE Everest 16.5.1 (Cisco NCS 4200 Series).

• Support for DS3 Smart SFP

DS3 Smart SFP supporting CEP ( VCoP Smart SFP) is a special type of optical transceiver whichencapsulates T3 frames on STS-1 channels into packet format.

Release Notes for Cisco NCS 4201 and Cisco NCS 4202 Series, Cisco IOS XE Everest 16.5.1 5

For more information, see Time Division Multiplexing Configuration Guide, Cisco IOS XE Everest16.5.1 (Cisco NCS 4200 Series).

• Unframed E1 for BCP over MLPPP

Bridge Control Protocol (BCP) is responsible for configuring, enabling and disabling the bridge protocolmodules on both ends of the point-to-point link. The BCP feature enables forwarding of Ethernet framesover serial networks, and provides a high-speed extension of enterprise LAN backbone traffic throughametropolitan area.When BCP is supported onMultilink PPP (MLPPP), it enables transport of EthernetLayer 2 frames through MLPPP.

For more information, see Cisco NCS 4200 Series Software Configuration Guide, Cisco IOS XE Everest16.5.1.
